Abstract: An operating method of a storage device including a nonvolatile memory device and a storage controller includes transmitting, by the storage controller, a set-feature command including error detection activation information to the nonvolatile memory device, transmitting, by the storage controller, a program command and write data to the nonvolatile memory device, performing, by the nonvolatile memory device, an error detection operation on the write data of a page buffer circuit before programming the write data to memory cells, in response to the program command, transmitting, by the nonvolatile memory device, the write data as error data to the storage controller when an error is detected in the write data, and programming, by the nonvolatile memory device, the write data to the memory cells when an error is not detected in the write data.

Abstract: A storage device includes a plurality of nonvolatile memory devices, a storage controller circuit and a leakage detection circuit. The storage controller circuit controls a plurality of nonvolatile memory devices, the storage controller circuit includes a plurality of connection terminals, each of the plurality of connection terminals is commonly connected to a corresponding set of pins, from among the pluralities of pins included in the plurality of nonvolatile memory devices, via a corresponding connection node, from among a plurality of connection nodes. The pins included in each set of pins have a same attribute. The leakage detection circuit is configured to determine whether leakage occurs at each set of pins based on the merged signal generated by the connection node connected to each set of pins, and configured to provide the storage controller circuit with a detection signal indicating a result of the determination.
